Abstract (en)
[origin: WO2010081450A1] The invention relates to a screw connection having a screw section and a nut screw-fitted thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received rotatably relative to the nut on said nut, wherein the intermediate disk has a grid which is effective in the circumferential direction and which, after installing the nut, forms a positive fit with a radially elastic catch that is fastened to the nut and formed by a sheet metal part. The elastically radially displaceable catch is pushed out of the grid by the screw-driving tool during the screw-driving process.
